Because all Ethernet cables are twisted, manufacturers use shielding to further protect the cable from interference. For example, Unshielded Twisted Pair (UTP) can easily be used for cables between your computer and the wall but you will want to use Foil Shielded Cable (FTP) for areas with high interference and running cables outdoors or inside walls.

There are different ways to shield an Ethernet cable, but typically it involves putting a shield around each pair of wire in the cable. This protects the pairs from crosstalk internally. Manufacturers can further protect cables from alien crosstalk with additional cable shielding beneath the sheath. The diagram below shows the different types of Ethernet shielding and the codes used to differentiate them.
